ISAAC TAYLOR, OF NEW YORK, N. Y.

FROSTING PLATES OF GLASS.

Speccation of Letters Patent No. 8,519, dated November 11, 1851.

To all whom t may concern Be it known that I, IsAAo TAYLOR, of New York, in the county and State of New York, have invented a new and useful Machine for Frosting and Embossing Plates ot Glass; and I hereby declare that the following is a. full and exact description.

To enable others to make and use my invention I proceed to describe its construction and operation, reference being had to the annexed drawings which make part of this speciication.

Figure l represents the machine as it is made for ordinary use. It is about ten feet long and four or ve feet wide. Fig. 2 end of the same. Fig. 3 transverse section.

The trough is placed on a couple of rockers which are attached to it and these are set upon other rockers reversed and the two are held in their relative position by permanent dowels in the bed rockers working in a slot made in the rockers of the trough.

There is a standard at one or both ends of the trough at the top of which is attached, by a pin or pivot, a connect-ing rod which may be moved by hand or by a crank. The object is to rock the trough back and forth. Vhen figures are to be embossed on glass by this process, they are first cut or ground outin intaglio. The sheet-s of glass are then laid on the bottom of the trough and secured in place (if need be) with the in-v taglio figures up. Then a quantity of pebbles about the size of hickory nuts, or filberts, and of all less sizes, with siliceous sand, is put over the glass and water poured upon it so that it will make a thin or creamlike mud of the sand. The machine is then rocked back and forth slowly just fast enough for the sand and pebbles to roll from side to side by the motion and this. is con--` ISAAC TAYLOR.
